How to creat mesh in Gambit for airfoil
 
hi,Everyone

i sanjay umarani doing my PG-in enginering analysis & design, as a part of my study i have to do project work. I have doing my project in CFD analysis of wind tubine airfoil design. I used eppler code to genert the x-y coordinates.

In this i have facing some proble to generate the airfoil in Fluent

1) the coordinate points of upper & lower are not equel ? for example -1098 airfoil of 61 cordinates

2) while meshing some c-gird type mesh to be created in that case the element points are not matching it is giving upper 36 & lower 35 it shoud not to be happened in fluent but givien that error why ?

if any one know this regard plesae tell me to what is wrong in this case

i have waiting your reply

HI:

Have a look at:

http://instruct1.cit.cornell.edu/courses/fluent/

It shows how to mes an airfoil

thanks for your reply

i have used the same site & same proble. But the co-ordinate i took was genrated by Eppler Code, in this case it is around 33 upper & 29 lower, if you make correction by making equal points, is their any change of shape will occure or what i have taken is correct i dont now.

After all correcting the co-oridante if you go head the it is giving meshing problem. As of my knowledg the mesh element should be equeal.

but in this case it is giving upper -76 & lower - 75 is it correct ?

if you know about plesae help me

Using Gambit, try to import your Eppler coordinate using ICEM Input.
